Command Line Search Strategies

Command Line searches enable users to conduct very specific and targeted line searches from any one of the Tyndale WorldCat search screens. To conduct a Command Line search you can add an Index Label as a prefix to one of your keywords.

Like the search limits in the Advanced Search screen the Index Label will tell the Tyndale WorldCat where to search for the terms in the record. For instance, if you are looking for C.S. Lewis' book "The Problem of Pain" you can use the following Command Line search for a title (ti:):

ti: problem of pain

You can also combine one or more search term using the Command Line search. For instance if you know the title of the book and the author's name you can use the following Command Line search for the title (ti:) and the author (au:):

ti: problem of pain au: lewis

The following is a list of the most common index labels used by researchers in a Command Line searches:

Index Label   Example   ..... Index Label   Example

Boolean Operators and Wildcards

Boolean operators enable researchers to combine one or more search terms in their command line searches. The Tyndale WorldCat search engine utilizes the following boolean operators:


Symbol Description and Example

AND + (plus sign)  
  Retrieves documents with all terms
  Example: "religion + education" searches for documents containing both terms "religion"  
  and "education"

OR | (pipe sign)    
  Retrieves documents with any single term or all terms
  Example: "teaching | instruction" searches for documents containing either/or and both
  terms "teaching" and "instruction"
NOT - (minus sign)  

  Retrieves documents with the first term and excludes terms that come after NOT
  Example: "literacy - childhood" searches for documents containing the term "literacy" but
  not the term "childhood"

Researchers can also use the following symbols to represent different alternative characters in their search terms. These symbols are called Wildcards and Truncations:

Command Symbol Description and Example
  Single character   #
  Replaces a single character in a search term
  Example: wom#n = woman or women

Multiple characters   ?   
  Replaces multiple characters in a search term
  Example: colo?r = color or colour or colonizer

Truncation *
  Truncates the search term
  Example: Canad* = Canada or Canadian or Canadiana
